Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] see first figure 1 As shown, the intelligent voice broadcast system based on environmental noise detection of the present invention is mainly composed of an intelligent voice broadcast module 11 , an environmental sound collection module 12 , a noise detection module 13 and a feedback module 14 . The intelligent voice broadcast module 11 is loaded on the intelligent vehicle-mounted system, controlled by the central control program of the intelligent vehicle-mounted system, and performs voice broadcast, such as the broadcast of the SMS mode and the navigation mode.

[0039] The environmental sound collection module is also loaded on the intelligent vehicle system, and is used for collecting the environmental sound in real time and converting the collected environmental noise into a digital signal during the voice broadcast proce...

Abstract

The invention discloses an intelligent voice broadcasting system and a method based on environmental noise detection. The method comprises the following steps: in a voice broadcasting process of an intelligent voice broadcasting module, acquiring environmental sound in real time and converting the intelligent environmental sound into a digital signal; detecting a noise signal and a voice signal in the digital signal, judging whether the noise signal affects voice broadcasting or not, outputting a regulating signal while judging that the noise signal affects the voice broadcasting.

Description

technical field [0001] The invention relates to a noise detection and response system, in particular to an intelligent voice broadcast system and method based on environmental noise detection, which is mainly suitable for the application of noise detection and TTS broadcast and the design of control circuits. Background technique [0002] Voice Activity Detection (Voice Activity Detection, VAD), also known as voice endpoint detection and voice boundary detection, refers to detecting the presence or absence of voice in a noisy environment. It is usually used in voice processing systems such as voice coding and voice enhancement to reduce Speech coding rate, saving communication bandwidth, reducing energy consumption of mobile devices, improving recognition rate, etc. [0003] As a new way of interaction, voice has been widely used in smart vehicle equipment. The driver can use voice to control the smart car equipment on the car to realize functions such as sending and receiv...
